Hey There!
ideal gas law :
PV = nRT
P = nRT/V
P = (1*0.082)(18+273)/(0.5) = 47.724 atm
For VDW :
(P + a(n/V)²)(V - nB) = nRT
P = nRT/(V - nB) - a(n/V)²
P = 1*0.082*(18+273) / (0.5-1*0.03219) - 1.345*( 1/0.5 )² = 45.62
P = 45.62 atm
Pdif = P2-P1 = 47.724 - 45.62 = 2.104 atm
Cheetah who is running with speed of 80 miles per hour then it is his instantaneous speed becaue i shows as in per hour speed..... hope it helps
Answer:
Volume of the concentrated solution, which is needed is 103.30 mL
Explanation:
Let's apply the formula for dilutions to solve the problem
Conc. Molarity . Conc. volume = Dil. Molarity . Dil volume
12.1 M . Conc. volume = 2.5 M . 500 mL
Conc. volume = (2.5 M . 500 mL) / 12.1M
Conc. volume = 103.30 mL
For us to accurately determine what compound
this is, additional info must be given. However I can suggest two compounds
which have molecular mass of about 30.07 g/mol.
1. It could be NO or nitric oxide.
The molecular mass is 16 + 14= 30 g/mol
But if we search the exact weight, it is 30.01 g/mol
2. It could also be (CH3)2 or ethane.
The molecular mass is 2*12+ 6*1= 30 g/mol
But if we search the exact weight, it
is 30.07 g/mol.
<span>So we could say it more likely to to be (CH3)2 </span>
Answer:
The correct answer is "A consumer is obtaining carbon by eating carbon-based molecules stored in a producer".
Explanation:
The animal is consuming the carbon present in the molecules stored in the grass. Plants process the carbon present in the soil along with other minerals. The animal, when it feeds on these plants, is consuming the carbon they obtained from the soil. Grasslands are defined largely by their use for grazing, which includes between 10 and 30 percent of soil carbon worldwide.
Have a nice day!
